Light-emitting assembly, display panel and display substrate

The utility model provides a light-emitting assembly, a display panel and a display substrate. The light-emitting device comprises a light-emitting unit and an optical function unit arranged on the light-emitting side of the light-emitting unit. The optical function unit comprises a transparent substrate, and the transparent substrate comprises a groove facing one side of the light-emitting unit; the groove comprises a first groove, and the first groove is filled with a first optical function material which is used for changing the color and/or wavelength of light emitted by the light-emitting unit. According to the light-emitting assembly, the display panel and the display substrate, the effect of reducing the total reflection phenomenon in the light emitting process can be achieved, the light emitting efficiency of the light-emitting assembly is improved, and therefore the display effect of the display panel and the display substrate is improved.
